Why is it so difficult to get mental health care in the US, when the country is clearly in a mental health crisis?

I am interested in this question given its relation to my own experiences and having to find proper care/treatment for myself. I myself have sought out mental health care since I was 13 for my anxiety and depression. With the pandemic and evolving needs, I am discovered that seeking mental health care is exceptionally difficult, given insurance coverage and available psychologists/therapists. I expect to find data on racial disparities, as well as information highlighting how the lack of available specialists has impacted how much help someone can receive. If I do happen to find information that goes against what I had initially expected to find, I’ll still include it in my paper and use it to present a different side to my research.
